Starlight Cove was the home to a lighthouse keeper Nathaniel and his beloved Virginia. After a pirate threat, Virginia was sent away, and the island was invaded. Nathaniel was captured and revealed that Virginia was returning, and the location of Nathan's wealth. In captivity, Nathaniel wrote to Virginia in the hopes of contacting Virginia to prevent her returning. The courier ship never arrived. Nathaniel was killed while taking a stand, and Virginia's fate remains unknown. 
Shortly after, the cove was renamed to Markhams Isle, after the pirate captain Markham. Some time later, they left the island for some unknown reasons and the station was fallen into ruin.
The Mechanists however rebuild the outpost and enforced it with massive iron constructions. They are using the isolated island for one of their most valuable projects: the Cetus Project. They pay special attention to the underground caves and tunnels and are busy in expanding them. To accelerate the progress of mining and tunneling they are using one of their newest inventions, a steam-driven drill.
Due to an earthquake or other disaster, parts of the underground facilities are flooded among other things the living quarters of Karras.
